Abstract
The invention discloses a carbon roaster flue wall guy brick precast block and a production method thereof. The carbon roaster flue wall guy brick precast block is produced by subjecting a mixture and an additive to mixing, stirring with water, molding by casting, curing and roasting, wherein the mixture comprises, by weight, 60-80% of bauxite chamotte, 5-20% of silicon carbide, 3-10% of silica fume, 3-10% of alumina powder, 3-10% of fine kyanite powder, 3-10% of pure calcium aluminate cement and 3-10% of metallic silicon, and the mass ratio of the mixture to the additive is 100 to 0.2-2. The production method includes mixing the mixture with the additive with the water added, pouring a mixed material into a mould and casting for vibration molding; roasting for 24-48 hours at 110-300 DEG C after natural curing so as to obtain a finished product. The carbon roaster flue wall guy brick precast block is low in production cost and simple in technology, properties such as the high-temperature creep rate and refractoriness under load can reach the levels of fired guy bricks, and the strength, the thermal-shock-resistant stability and sulfide corrodibility are superior to those of the fired guy bricks.
Description
Technical field
The present invention relates to carbon roasting furnace technical field, relate in particular to a kind of carbon baking furnace flame path wall and draw brick prefabricated
Block and preparation method thereof.
Background technology
Flue wall draws brick to be the key components of carbon baking furnace flame path wall, and the quality of its quality directly affects flue wall
Life-span, therefore increasingly come into one's own the service life that flue wall draws brick.
Flue wall draws brick generally to use, and refractoriness under load is high, high temperature creep rate is low burns till high-alumina brick material, burns till temperature
Degree is generally at about 1400 ~ 1500 DEG C, but produces the high-alumina brick that burns till per ton and need to consume natural gas 90 ~ 100m3Or 350Kg coal,
Discharge 900Kg CO2 , causing great energy waste and environmental pollution, this is not correspond with the trend of modern hot industry development
's.Meanwhile, in roaster normally works, baking furnace flame path wall draw brick to remove refractoriness under load to be had is high, high temperature creep rate is low
Performance outside, the harshness such as infiltration and the erosion that to be also faced with the acidic high-temperature gases such as the variations in temperature colded and heat succeed each other and sulfide
Environment, flue wall draws brick gradually to there will be crackle, deformation, and cause flue wall to sink, cave inward etc. changes, and affects roaster
Normal intensification, the quality of anode carbon block also can produce fluctuation.Drawing the performance of brick for promoting flue wall further, Some Enterprises is attempted
Use the low pre-formed flue wall of cement steel fiber castable draw brick to improve its heat-resistant knocking stability, but in terms of resistant to corrosion imitate
Fruit is the most undesirable, is quickly corroded in above-mentioned working environment, materials'use restricted lifetime.
Summary of the invention
It is contemplated that overcome prior art defect, it is therefore intended that provide a kind of carbon baking furnace flame path wall to draw brick prefabricated section
And preparation method thereof, its performance such as high temperature creep rate, refractoriness under load reaches to burn till the level drawing brick, its intensity, anti-thermal shock
The aspect of performances such as stability and resisting sulfide erosion are substantially better than to burn till and draw brick.
To achieve these goals, the technical scheme is that
A kind of carbon baking furnace flame path wall draws brick prefabricated section, described carbon baking furnace flame path wall to draw brick prefabricated section by compound with outer
Add that agent is blended, the stirring that adds water, moulding by casting, maintenance, baking form；Described compound is ripe by the alumine of 60 ~ 80wt%
Material, the silicon ash of the carborundum of 5 ~ 20wt%, 3 ~ 10wt%, the kyanite fine powder of the alumina powder of 3 ~ 10wt%, 3 ~ 10wt%, 3 ~
The pure calcium aluminate cement of 10wt%, the metallic silicon power composition of 3 ~ 10wt%, described additive is 100:0.2 with the mass ratio of compound
~2。
As the improvement to technique scheme, the described Al in bauxite chamotte2O3>=75wt%, alumine is ripe
The particle diameter ＜ 8mm of material.
As the improvement to technique scheme, the described SiC >=97wt% in carborundum；The particle diameter ＜ of carborundum
1mm。
As the improvement to technique scheme, described silicon powder SiO2≥92wt%；Particle diameter ＜ 0.005 μ of silicon powder
m。
As the improvement to technique scheme, described alumina powder Al2O3≥99wt%；The particle diameter ＜ 44 of alumina powder
μm。
As the improvement to technique scheme, described kyanite fine powder Al2O3≥53wt%；The particle diameter of kyanite fine powder
＜ 0.074mm.
As the improvement to technique scheme, described pure calcium aluminate cement Al2O3>=70wt%, pure calcium aluminate cement
Particle diameter ＜ 44 μm.
As the improvement to technique scheme, described metallic silicon power Si >=97wt%；The particle diameter ＜ of metallic silicon power
0.074mm。
As the improvement to technique scheme, described additive is the explosion-proof fiber of water solublity, sodium tripolyphosphate, six inclined phosphorus
One or more in acid sodium, sodium citrate, sodium lignin sulfonate.
The present invention also provides above-mentioned carbon baking furnace flame path wall and draws the preparation method of brick prefabricated section, the work of this preparation method
Skill step is:
(1) bauxite chamotte, carborundum, silicon ash, alumina powder, kyanite fine powder, pure calcium aluminate cement, metallic silicon, are chosen
Powder does raw material, chooses in the explosion-proof fiber of water solublity, sodium tripolyphosphate, sodium hexameta phosphate, sodium citrate, sodium lignin sulfonate
Plant and make additive；
(2), above-mentioned compound is mixed with additive, add water and stir, obtain thickness material；
(3) the thickness material, by adding water stirred joins in mould, with cast vibration formation method piecemeal molding；
(4), natural curing 24 ~ 48h；
(5), under the conditions of 110 DEG C ~ 300 DEG C, toast 24 ~ 48h, obtain carbon baking furnace flame path wall and draw brick prefabricated section.
The present invention has the advantage that with good effect:
Present invention process is simple, through dispensing, add water, stir, pour into a mould, toast after can use, decrease loaded down with trivial details the adding of burnt brick
Work operation, the brick that draws of the present invention burns till without high temperature simultaneously, utilizes its temperature by bonding agent, surpasses in roaster roasting process
Fine powder and excellent additive complete sintering voluntarily, saved resource, have protected environment.During moulding by casting, silicon powder
